CLEANING AND MAINTENANCE OF CERAMIC-GLASS HOB
Ceramic glass hob should be cleaned only when completely cooled down,
preferably after each use, otherwise even the slightest stains remaining after
cooking may burn into the hob surface with each following use.
For regular maintenance of ceramic-glass hob use special cleansing agents,
produced in such way to create protective film upon the surface.
Before each use, wipe the dust and other particles from the hob, they may scratch
the surface (Fig. 1).
Caution: use of steel wool, abrasive cleaning sponges, and abrasive detergents can

scratch the surface of the hob. The surface may also be damaged by the use of
aggressive sprays and inappropriate liquid chemicals (Fig.1 and 2).
Pattern marks can be erased by the use of aggressive cleansing agents or rough
and damaged cookware bottoms (Fig. 2).
Minor stains are removed with moist soft cloth; after that the surface should be
wiped dry (Fig. 3).
Water stains are removed with gentle vinegar solution, but you must not wipe the
frame with it (certain models only), since it may lose its glow. Never use any

aggressive sprays or limestone removers (Fig. 3).
Major stains are removed with special ceramic-glass cleansers.
Follow strictly the manufacturer's instructions.
Be careful to remove any remains of cleansing agent from the hob surface,
otherwise they will be heated during the next use and can damage the hob (Fig. 3).
Stubborn and burnt stains are removed with special ceramic-glass scraper. Be
careful, however, not to touch the hotplate surface with the scraper handle (Fig. 4).

Handle the scraper with utmost care to avoid injuries!
Sugar and sugar containing food may permanently damage the ceramic-glass hob
surface (Fig. 5), so the remains of sugar and sugar containing food must be
scraped off from the hob surface immediately, when the hotplates are still hot
(Fig. 4).
Discoloring of ceramic-glass hob has no effect whatsoever on its operation and
stability. In most cases, it appears as the consequence of burnt in food remains, or
as a result of dragging pots and pans (especially aluminium or copper bottom
cookware) across the surface, and such discoloring is rather hard to remove.
